ABSTRACT

A  Scaevola  plant particularly distinguished by violet-blue flowers with yellow-white eyes, a mid-season, continuous and an abundant flowering response, medium green foliage with purplish stem ends, a vigorous growth habit with a medium to tall plant habit, a decumbent to trailing plant habit with ascending stem ends, a rounded, bushy and well-branched plant habit and good heat tolerance, is disclosed.

GENUS AND SPECIES

Scaevola aemula

VARIETY DENOMINATION

‘Bomy Bule’

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Scaevola, botanically known as Scaevola aemula and hereinafter referred to by the cultivar name ‘Bomy Bule’. The new cultivar originated from a hybridization made in July 2003 in Gilroy, Calif. The female parent was ‘180’, a proprietary violet-flowered Scaevola plant (unpatented), while the male parent was ‘999’, a proprietary violet-flowered Scaevola plant (unpatented).

The new cultivar was created in July 2003 in Gilroy, Calif. and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Gilroy, Calif. and Hillscheid, Germany over a one and one-half-year period. The plant has also been trialed at Gilroy, Calif. and Hillscheid, Germany. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this cultivar have been applied for in Canada on Mar. 29, 2005.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of the new cultivar when grown under normal horticultural practices in Gilroy, Calif. and Hillscheid, Germany.

-   -   1. Violet-blue flowers with yellow-white eyes;     -   2. A mid-season, continuous and an abundant flowering response;     -   3. Medium green foliage with purplish stem ends;     -   4. A vigorous growth habit with a medium to tall plant habit;     -   5. A decumbent to trailing plant habit with ascending stem ends;     -   6. A rounded, bushy and well-branched plant habit; and     -   7. Good heat tolerance.

DESCRIPTION OF THE PHOTOGRAPHS

This new Scaevola plant is illustrated by the accompanying photographs which show overall plant habit including inflorescences, buds and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photos are of a 26-week-old plant grown in a greenhouse in an early Fall trial setting.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Bomy Bule’. The data which define these characteristics were collected from asexual reproductions carried out in Hillscheid, Germany. Rooted cuttings were planted into 12-cm plastic pots in early March and pinched once. In late May, the plants were transplanted to outdoor hanging baskets that were situated under light rain protection. The plant history was taken on 11-week-old plants grown in a greenhouse and on 26-week-old plants grown outdoors in Hillscheid, Germany in Summer 2005. Observations were made in early September 2005 when the plants had reached their maximum size. Color readings were taken under natural light. Color references are primarily to the RHS Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001 edition).

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS

‘Bomy Bule’ differs from the female parent ‘180’ (unpatented) in that ‘Bomy Bule’ has lighter colored flowers, broader leaves and a more compact plant habit than ‘180’.

‘Bomy Bule’ differs from the male parent ‘999’ (unpatented) in that ‘Bomy Bule’ has deeper violet flowers and has an earlier flowering response than ‘999’. Additionally, ‘Bomy Bule’ has a more compact plant habit than ‘999’.

‘Bomy Bule’ differs from the commercial variety ‘Fancy’ (U.S. Plant Pat. No. 9,867) in that ‘Bomy Bule’ has longer stems and longer and more narrow leaves that are directed at almost right angles to the stem, while ‘Fancy’ has shorter, spoon-shaped leaves that partly cover the stem in an overlapping arrangement. Additionally, the flowering stems of ‘Bomy Bule’ are longer with a looser arrangement of flowers, while the flowers of ‘Fancy’ have a tighter arrangement and are closer to the ends of the flowering stems.

‘Bomy Bule’ differs from the commercial variety ‘Newon’ (U.S. Plant Pat. No. 10,584), in that ‘Bomy Bule’ has narrower and more serrated leaves than ‘Newon’. Additionally, ‘Bomy Bule’ has more basal branching than ‘Newon’.
